PhysicsEasysingle choice

The rope shown in the figure is wound around a uniform cylinder of mass $4 kg$ , about the axis of the cylinder. If the cylinder rolls without slipping, then the linear acceleration of its centre of mass is

Options:

Answer:

Solution:

For rotational motion

$τ = I α$

$\Rightarrow F (2 R) = \frac{3}{2} M R^{2} (\frac{a}{R})$

$\Rightarrow a = \frac{4 F}{3 M} = \frac{4 (20)}{3 (4)} = 6 .7 m s^{- 2}$
